/6 problems

Remove the fuel filter, not which way the fuel is flowing through it. Then empty the filter and take and tap the filter INLET end on a work bench. I bet all kinda crap comes out. If it does, drop the tank and rinse it out til the water comin our is CLEAR. Then dry it out good and put it back in. You'll probably need to clean the carb out too. Might end up needin a kit. Tappin the fuel filter will confirm it. That's the cheapest place to start. If it's dirty, you know what to do.
